1.	Although geometries of NH_(3) and H_(2)O moleculesare distorted tetrahedral, bond angle in water is less than that of ammonia. Discuss.
Answer» Solution :`NH rarr NH_(3)` `H_(2)O rarr H_(2)O:` Because of two lone pair of electrons on O-atom, repulsion on bond PAIRS is greater in `H_(2)O` in COMPARISON to `NH_(3)`. THUS, the bond angle is less in `H_(2)O` molecules.
